Product details

What this Class D amp brings to the board

The Maxim Integrated MAX98400AETX+ is a 2-channel (stereo) Class D audio amplifier rated for 20W per channel into an 8Ω load. It runs on an 8V to 28V supply rail, which gives you flexibility across 12V automotive audio, 24V industrial PA systems, and 18V portable battery-powered speakers. The 36-TQFN (6x6) package with exposed pad keeps the heat managed without a big heatsink — useful when board space is tight.

Lifecycle and sourcing reality

The MAX98400AETX+ is listed as Active in production — no last-time-buy clock ticking, no EOL notice to worry about for new designs. ROHS3 compliant, so it passes the environmental specs for EU and global markets. Sourced through independent distribution; availability and current pricing confirmed at quote time against an RFQ.

Frequently asked questions

What is the output power per channel of MAX98400AETX+?

20W per channel into an 8Ω load, stereo (2-channel).

What package does MAX98400AETX+ come in?

36-TQFN (6x6) with exposed pad, surface-mount.

What are the differences between MAX98400AETX+ and MAX98300?

The MAX98400AETX+ delivers 20W x 2 @ 8Ω, while the MAX98300 is a lower-power mono Class D amp typically used for portable speakers. The MAX98400AETX+ also includes differential inputs and a wider 8V to 28V supply range, making it better suited for automotive and industrial audio.
